Hi, Linux Jellyfin 10.6.4 on CentOS 7 installed via RPM here.
I’ve just barely started ripping BD’s with makemkv, and the first several titles work beautifully in Jellyfin.
I got to my Star Wars collection for episodes 1-6, and for some reason they all start playing on chapter 2, skipping the fox/lucasfilm/textcrawl and the first minute or two of action. Playing the title on VLC starts at the beginning as would be expected. I tried both as a BDMV folder and an MKV file. Both work on VLC as expected, but start in the same place which looks to be the start of the second chapter of the main title on Jellyfin.
